The purpose of study was to determine the effect of vitamin C supplementation on maximum physical activity on the total of leukocytes. Research method used a quasi-field experiment with pre-test design and post-test control group design. The study subjects consisted of four male non-athletes, aged 20-22 years. The number of leukocytes was measured before and after vitamin C supplementation with a dose of 100 mg and 500 mg in maximum activity, namely running to fatigue. Data normality was tested by Kolmogorov Smirnov and paired sample t-test was used to test for differences in the total of leukocytes before and after vitamin C supplementation. The results showed that the average number of respondents' leukocytes increased after maximal physical activity (∆ = 6,775) and after vitamin C supplementation 100 mg (∆ = 1300) and 500 mg (∆ = 550). Paired t-test showed a significant difference (p = 0.019) between the total of leukocytes before and after maximum physical activity. There was no significant difference between the supplementation of vitamin C at a dose of 100 mg (p = 0.09) and a dose of 500 mg (p = 0.95) on the total of leukocytes before and after maximum physical activity. So, it is concluded that maximum physical activity increases the number of leukocytes. However, there was no difference in the number of leukocytes before and after maximum physical activity in the supplementation of 100 mg and 500 mg of vitamin C

“…Kadar hemoglobin yang cukup dapat mempengaruhi jumlah oksigen dalam darah, memungkinkan lebih banyak oksigen untuk dikirim ke otot dan meningkatkan kebugaran jasmani. Selain itu, vitamin C dapat membantu meningkatkan sistem imun dan performa tubuh sehingga dapat mencegah adanya kelelahan dan kelemahan otot serta dapat melindungi sel dari paparan radikal bebas (Dewi & Wirjatmadi, 2018;De Moura et al, 2014).…”

“…Pada 200 ml jus jambu biji merah mengandung 6,8 mg zat besi dan 321,3 mg vitamin C sedangkan pada jus jambu kristal mengandung 6,9 mg zat besi dan 423 mg vitamin C berdasarkan hasil pemeriksaan laboratorium di Laboratorium Pangan Che-Mix Yogyakarta. Kandungan zat besi dan vitamin C pada jambu biji merah dan jambu kristal cenderung lebih tinggi dibandingkan dengan buah yang lain (Dewi & Wirjatmadi, 2018). Menurut Angka Kecukupan Gizi (AKG) tahun 2019, kebutuhan zat besi pada remaja putri sekitar 15 mg dan vitamin C sekitar 75 mg per hari apabila mengonsumsi perpaduan tablet tambah darah dan jus jambu biji merah maupun jus jambu kristal sudah memenuhi Angka Kecukupan Gizi (AKG) remaja usia 10-17 tahun dengan >100% (Kemenkes RI, 2019).…”

Anemia often occurs in female adolescents cause by iron deficiency. Adolescents are diagnosed anemia if the hemoglobin level is <12 g/dl. Someone who has anemia is prone to have low physical fitness. Consumption of foods that are high in iron and vitamin C such as guava juice can help improve physical fitness. The aim of this study was to analyze the effect of red guava juice and crystal guava juice consumption on physical fitness in female adolescents with anemia. The design of this study was a quasi-experimental with pre and post-test control group design with 36 subjects divided into 3 groups, namely control (iron tablets), P1 (iron tablets + red guava juice), P2 (iron tablets + crystal guava juice). Red guava juice and crystal guava juice given 200 ml per day for 30 days. The physical fitness test uses the Harvard Step Test method with a Physical Efficiency Index assessment. Physical fitness before and after control group had a difference of 1.84±15.86, the difference in P1 group was 17.20±20.35, and the difference in P2 group was of 19.69±15.58. Based on the results of statistical tests, it was found that there were differences in the three groups before and after the intervention p=0.031 (p<0.05). Giving red guava juice and crystal guava juice can be an alternative to improve physical fitness in female adolescents with anemia, but crystal guava juice is the most effective in increasing physical fitness in female adolescents with anemia.

“…Many micronutrients are used together with iron to improve the absorption of nutrients, including folic acid, vitamin A, vitamin C, zinc, vitamin B12, and others (Das et al, 2019;Tam et al, 2020). Vitamin C helps accelerate iron absorption in the body (Dewi & Wirjatmadi, 2017). Vitamin C also plays a role in moving iron into the blood and mobilizing iron stores, especially hemosiderin in the spleen (Drouin et al, 2011).…”

Regarding nutrition, providing proper food intake can produce optimal physical conditions and provide sufficient energy. This research aimed to prove that combining iron tablets and 1000 mg of vitamin C can increase hemoglobin levels and maximum oxygen volume in female athletes in martial arts. This research used an experimental group design by using a randomized post-test-only control group design. It used 40 female athletes divided into four groups and carried out for 12 weeks. The control group was given a placebo, treatment group one was given iron tablets three times a week, treatment group two was given 1000 mg of vitamin C three times a week, and treatment group three was given a combination of iron tablets and 1000 mg vitamin C. The results show that the mean of hemoglobin levels in the group given iron tablets is 13.23 ± 1.09 g/dL, vitamin C is 12.69 ± 0.89 g/dL, and a combination of iron tablets and vitamin C is 14.50 ± 1.40 g/dL significantly higher (p < 0.05) than the control group, namely 11.93 ± 1.08 g/dL. The average maximum oxygen volume level in the group given iron tablets is 41.24 ± 0.52 ml/Kg/minute, vitamin C is 40.58 ± 0.66 ml/Kg/min, and a combination of iron tablets and vitamin C is 43.33 ± 0.41 ml/Kg/min which is significantly higher (p < 0.05) compare to the control group’s average of 38.33 ± 0.42 ml/Kg/min. It concludes that giving iron and vitamin C tablets to female martial arts athletes can significantly increase hemoglobin levels and maximum oxygen volume. Therefore, iron and vitamin C tablets are proven to contribute to overcoming the problem of anemia in women and are able to increase the cardiovascular capacity of athletes.
